Hi…
Can anyone tell me which mikrotik Mini PCI card that support 40Mhz Turbo Channel Width on 2GHz Band
It’s allowed for 802.11a. Isn’t better to use 802.11n instead?
hi
The best offer for your situation, use mini PCI card that support “802.11 N”.
However “802.11 N” not support 40Mhz channel width, That support 20Mhz central + 20Mhz extension channel width.
… and 20Mhz + 20MHz equals…? … to 40MHz (probably just by coincidence only… 
)
Almost all cards with AR5213 and AR5414 chip, it means all cards with A/G-Turbo. Normally non-N chispet cards. Now only R52H from MT offer.
Why you need 40MHz?
